Method for programming the perpetual calendar of a watch and a watch for implementing such a process

ABSTRACT

A process for programming the perpetual calendar of a watch with analog time display is effected using elements incorporated in the watch. The hand of the watch and the position of the hand is used to indicate the steps of the programming. The operation of the stem places the watch in the program mode. If it is required to program three parameters, namely, the number of the year in a four year cycle, the number of the month of the year and the day of the month; and if the watch has a hand setting stem with three positions, each parameter to be programmed is allocated to a position of the stem and the parameters to be programmed are read from the second hand by allocating to the latter real steps corresponding to stopping positions and non allowable steps corresponding to non stopping positions.

The present invention concerns a process for programming a perpetualcalendar of a watch featuring a perpetual calendar and an analogicaltime display, in which is programmed at least one of the followingparameters of this perpetual calendar: number of the year in a cycle offour years, name or number of the month in the year, day of the month,this watch comprising a case, at least an hour hand, a minute hand andeventually a seconds hand, at least one motor driving these handstogether with a quartz-controlled electronic command circuit, means ofdisplaying at least the day of the month and eventually the name of theday, a time-setting rod and an activating mechanism to enter aprogramming mode, a selecting mechanism and an adjusting mechanism tomodify said parameters to be programmed and a display mechanism tovisualize said parameters.

It also concerns a watch of the type featuring a perpetual calendar andan analogical time display, comprising a case, at least an hour hand, aminute hand and eventually a seconds hand, at least one motor drivingthe hands and a quartz-controlled electronic command circuit, means ofdisplaying at least the day of the month and eventually the name of theday, a time-setting rod and the activating mechanism to enter theprogramming mode, the selecting mechanism and the adjusting mechanism tomodify the parameters to be programmed, these parameters being thenumber of the year in a cycle of four years, the name or the number ofthe month of the year and the day of the month, and the displaymechanism to visualise said parameters, this watch being designed tomake use of the above process.

The perpetual calendar of a watch displays the day of the monthcorrectly, allowing for the irregularity of the number of days in themonths of the year and also for leap years which have an extra day, i.e.the 29th of February.

All this represents a cycle of four years which does not present anyadditional irregularities before the year 2100 which will not be a leapyear, because of the fact that all the years denoting a century, exceptthose whose first two figures are divisible by four, are not leap years.

To correct these irregularities in a four year cycle, a system must beused where the moment of the correction, whether it be the end of themonth and the value to be corrected, whether it be the number of days ofeach month during four years, are defined.

For a mechanical watch it is sufficient to add to the display of the dayof the month, the name of the month and the number of the year in acycle of four years according to the following scheme:

No. 0 for the leap years i.e. 1984, 1988, 1992, 1996

No. 1 for the years 1985, 1989, 1993, 1997

No. 2 for the years 1986, 1990, 1994, 1998

No. 3 for the years 1987, 1991, 1995, 1999.

The No. of the years corresponds to the remainder from the division byfour of the number defining these years.

For a mechanical watch, it is not possible to hide from the wearer thename of the month and the number of the year because this type of watchmay stop, for example if the watch is not worn for a certain period,when it is put on again it is necessary to re-date the calendar.

For quartz watches, the situation is completely different given thatthey continue to function even when they are not worn. Therefore it ispossible to consider the name of the month and the number of the year asparameters uniquely accessible by the manufacturer or by a specialist,for example when the battery is changed. By their very nature,electronic systems permit such a conception whereas the mechanicalsystems can not.

With the aim of unifying the system, it is preferable to add a thirdparameter, by way of the day of the month, because this avoids adetection of the position of the day of the month disc to define themoment of the correction.

In summary, a watch featuring a perpetual calendar generally comprisesthree parameters to be programmed which are respectively, the number ofthe year in a cycle of four years, the name or the number of the monthof the year and the day of the month which defines the moment of thecorrection.

These three parameters are memorised by the electronic circuit and theoperation which consists of entering them in the memory is called"programming (setting) the watch".

In existing watches, the programming mode is initiated by means of anapparatus or a device separate from the watch which is only possessed byspecialists, i.e. the manufacturer and those watch sellers who arelicensed dealers of the manufacturer's make. This is a drawback whichcauses complications for the customer.

The present invention proposes to obviate this drawback by using aprocess which makes it possible to abolish the need for a special deviceto ensure the programming of the perpetual calendar of an electronicanalogical watch.

With this aim, the process according to the invention is characterisedin that the programming operations are effected exclusively by the saidactivating, selecting, adjusting and display mechanisms which areintegral with the watch.

According to a particular embodiment of the process, the parameters tobe programmed are visualised by means of the hands of the watch and theprogramming mode is entered by means of the time-setting rod.

Preferably, the programming mode is entered by manipulating thetime-setting rod in a predetermined way which is different from thatrequired to set the time.

The programming mode may also be entered by means of a contactassociated with an electronic circuit or by means of a push piecemounted on the case of the watch.

In this embodiment of the process, the parameters to be programmed arevisualised by means of one of the hands of the watch, the movement ofthis hand is ordered so that some determined number steps are real andcorrespond to the stop positions of the hand and that some determinednumber steps are forbidden, these steps not corresponding to the stoppositions of the hand, and the stop positions of the hand are coded sothat they correspond to the said parameters of the perpetual calendar.

Preferably, the parameter corresponding to the number of the yearcomprises the following numbers: 0, 1, 2, or 3, the real steps being thefollowing: 15 for the number 1, 30 for the number 2, 45 for the number3, and 60 for the number 0, all the other steps being forbidden. Theparameter corresponding to the numbers of the month comprises thenumbers from 1 to 12, the real steps being the following: 5 for thenumber 1, 10 for the number 2, 15 for the number 3, 20 for the number 4,25 for the number 5, 30 for the number 6, 35 for the number 7, 40 forthe number 8, 45 for the number 9, 50 for the number 10, 55 for thenumber 11, and 60 for the number 12, all the other steps beingforbidden. The parameter which corresponds to the day of the monthcomprises numbers ranging from 1 to 28, 29, 30 or 31 depending on themonth, the real steps being the following: 1 for the number 1, 2 for thenumber 2, . . . and 31 for the number 31, all the other steps beingforbidden.

The watch according to the invention is characterised in that the saidactivating, selecting, adjusting and display mechanisms are integralwith the watch.

According to one form of a preferred embodiment, the said displaymechanism comprise at least one of the hands of the watch, and the saidactivating mechanism comprise the time-setting rod of the watch or acontact associated with an electronic circuit or a push piece mounted onthe case of the watch.

Preferably, the time-setting rod, comprises at least two positions, eachone being associated with a parameter to be programmed, these twoparameters being the year and the month.

The present invention will be better understood by referring to thedescription of an example of the preferred embodiment and to the annexeddrawings in which:

FIG. 1 represents a schematic view illustrating the process of orderingthe programming of the parameter "number of the year" and means ofvisualising this parameter,

FIG. 2 represents a schematic view showing the process of ordering theprogramming of the parameter "month of the year" and means ofvisualising this parameter,

FIG. 3 represents a schematic view showing the process of ordering theprogramming of the parameter "day of the month", and means ofvisualising this parameter, and

FIG. 4 illustrates, in the form of a block-schema the electronic circuitof the watch defined above.

In the watch proposed above, the electronic circuit is capable ofassuming its normal functions, which consist of driving the progressionof the hands and displaying the various indications of the calendar andalso, of functionning in programming mode, i.e. to permitting thememorising of the above mentioned parameters.

For this programming mode to be possible, it is essential to have amechanism which allows the switching of the electronic circuit from thenormal operating mode to the programming mode.

In addition, to allow the control of this programming by the operator,the watch must include means of allowing the display of the parametersto be programmed.

According to one preferred embodiment, the visualising of the parameterto be programmed is effected by means of a hand of the watch. The handchosen is preferably the seconds hand.

The passage from the normal operating mode to the programming mode maybe brought about by a contact associated with an electronic circuit.This contact could be a circuit breaker mounted on the printed circuit,a circuit breaker linked with the case, for example initiated by theremoval of the back of the case etc. This change of mode may also bebrought about by a push piece mounted on the case of the watch.

The solution which has been found to be the best consists of startingthe programming mode by means of the time-setting rod of the watch. Toavoid the accidental start of the programming mode by a non experiencedwearer, a particularly special manipulation of the time- setting rod isused to enter the programming mode, this manipulation beingfundamentally different from the usual manipulations required for theroutine operations of time adjustment. In the particular case where thetime-setting rod comprises three positions, the programming mode may beentered by a manipulation which consists of pulling this time-settingrod successively from position 1 to position 2 to position 3, to returnrapidly to position 1 and to repeat the cycle a second time. If themanipulation is correct and if the programming mode is started, theseconds hand moves rapidly and stops on position 15, position 30,position 45 or position 60. If the operator does not see this rapidmovement of the seconds hand, he will deduce that the manipulation tostart the programming mode was incorrectly carried out and that it mustbe repeated.

In the example illustrated by FIGS. 1, 2 and 3, the time-setting rod 10of the watch 11 equipped with a seconds hand 12 comprises threepositions 1, 2, and 3. Position 1 corresponds to the first parametermentioned above, i.e. the number of the year in a cycle of four years,position 2 corresponds to the second parameter, i.e. the number of themonth in the year and position 3 corresponds to the third parameter,i.e. the number of the day of the month.

When operating normally, the seconds hand takes sixty steps for eachcomplete cycle, and if each step corresponds to a number from 1 to 60,this hand can program the numbers from 1 to 60 included. For numberssmaller than 60, a combination of real steps and forbidden steps isused, real steps being those on which the hand stops and the forbiddensteps being those over which the needle passes without stopping.

In FIG. 1, the time-setting rod 10 is in position 1, i.e. in programmingmode, the number of the year may be programmed. Given that a cyclecomprises four years to which the numbers 0, 1, 2 or 3 are attributed,the real steps of the seconds hand 12 are 15 for the number 1, 30 forthe number 2, 45 for the number 3 and 60 for the number 0 which, asmentioned before, corresponds to the leap years. All other steps areforbidden.

When the time-setting rod 10 is in position 2 as shown in FIG. 2, theparameter to be programmed is the number of the month which varies from1 to 12. Accordingly, the following real steps have been chosen: 5 forthe number 1, 10 for the number 2, 15 for the number 3, 20 for thenumber 4, 25 for the number 5, 30 for the number 6, 35 for the number 7,40 for the number 8, 45 for the number 9, 50 for the number 10, 55 forthe number 11 and 60 for the number 12. All other intermediate steps areforbidden.

FIG. 3 shows the programming of the days of the month. The time-settingrod 10 is in position 3. The real steps going from 1 to 31 have beenchosen so that the seconds hand can occupy all the positions going from1 to 31. All the other steps are forbidden.

It is observed that according to this embodiment, each parametercorresponds to a well defined position of the time-setting rod and to avery characteristic combination of real steps and of forbidden steps ofthe seconds hand.

For example, after a change of battery, the pressing of the circuitgenerates the state: "January 1st of a leap year". From thisinformation, the operator has to programme the complete date by turningthe crown anti-clockwise for each position of the rod. For example, toprogramme the date August 4th. 1987, the following operations must becarried out:

a) enter the programming mode by one of the previously described ways

b) bring the time-setting rod into position 1, then turn the rod untilthe seconds hand is on 9 o'clock, i.e. in the position of the real step45 which corresponds to the year number 3.

c) bring the time-setting rod into position 2, then turn the rod untilthe seconds hand is on the position 8 o'clock, i.e. on the real step 40which corresponds to the eighth month of the year.

d) bring the time-setting rod into position 3, then turn it until theseconds hand is on the real step 4 corresponding to the fourth day ofthe month.

If the operator goes past the required value he must continue turning inthe same sense until the correct value is reached. A rotation of thecrown in the opposite sense, i.e. in a clockwise direction is invalid.This process allows the crown to be screwed on without changing theprogramming.

It is also noted that exiting from the programme occurs automaticallyafter a predetermined delay, for example ten seconds after the lastmanipulation.

If a correction of the date of the month or the name of the day isnecessary, for example when the battery is changed, this is carried outby the normal means of correction of the day and name of the month.

The operator must, of course, check that the day displayed correspondsto the day programmed.

At the moment of entry into the programming mode, the said correctionmeans, i.e. correction of the time, the correction of the day of themonth and eventually that of the time-zone, are unusable.

It is understood that various modifications could be applied to theabove watch. The programming of the three parameters by means of thetime-setting rod is facilitated by the fact that this rod has threepositions. In the case of a rod which has two positions, one of theparameters can be programmed by another element or by a sequentialarrangement, a push piece or any other known device.

In this last case, the programming of the day could be replaced by adetector of the position of the day disc.

Referring to FIG. 4, the electronic circuit comprises all the elementsnecessary for the execution of a perpetual calendar, i.e. tosuccessively enter the years, the months and the days in the electronicmemory by means of the switch I which allows entry into the programmingmode, the crown 20 connected to the time-setting rod 10 which has threepositions, a position and rotation sensing element 21 which generatesrotation impulsions of the crown in tho positive sense, to deliver theseimpulsions F, and the seconds hand 12 whose position successivelyindicates the year, the month and the day of the month as described forthe preceding figures. The command mechanisms for the hour hand and theminute hand, together with the command mechanism of the day discs andeventually of the name of the day, which are well known by those skilledin the art, are not represented in this scheme.

Referring to this scheme, the electronic circuit comprises first of alla quartz resonator 23 which is a standard quartz at a nominal frequencyof 32.768,0 Hz. It is associated with an oscillating block 24 whichmaintains and emits oscillations of the nominal frequency and suppliesan alternating signal at this frequency to a frequency divider 25 ofnine layers of dividers by two. At its exit it provides a logical signalof 64 Hz. This signal is transmitted to a frequency divider 26 of sixlayers of dividers by two and to a door "AND" 27. This divider 26provides at its exit a signal of 1 Hz, i.e. a period of one second, to acounter 28, called a sixties counter, which keeps count of the secondsor in other words constitutes the permanent electronic memory of aprecise second. This counter is connected to two dividers 29 and 30which divide respectively by 60 and 24. The divider 30 allows theprovision at its exit of one impulsion C_(D) per twenty four hours.

The counter 30 is connected to a divider 31 called day counter whichcounts from 1 to 28, 29, 30 or 31 according to the command P whichprovides it with a block 34 called perpetual algorithm which will bedescribed below. Each impulsion C_(D) increases the counter by one unit:in case the capacity is exceeded (i.e. 28, 29, 30 or 31) the new valuetaken is 1 and a signal C_(C) is generated at its exit to command acounter of months 32 which counts from 1 to 12. It is increased by theentry signal C_(C) ; in case its capacity is exceeded (12), the newvalue taken is 1 and a signal C_(B) is generated at its exit to commanda year counter 33. The counter 32 also furnishes its own state (1 to 12)to the perpetual algorithm 34.

The year counter counts from 0 to 3, (the year 0 being a leap year). Itis increased by the entry signal C_(B), when the capacity (3) isexceeded, the new value taken is 0. This counter also furnishes its ownstate (0 to 3) to the perpetual algorithm 34.

The perpetual algorithm 34 comprises the means necessary for thecalculation of the number of days, of the month, of the year which it isprovided with by the counters 32 and 33. For example year 0, month 2(February in a leap year) corresponds to 28 days. The signal P providedby this block 34 to the day counter 31 gives the maximum counting valueto this latter which is, in the above example, 28.

The counter 33 is coupled with a year coder 35 which comprisescombinative logical elements which allow the correspondence of thevalues from the year counter 33 with the values corresponding to theimage of the position of the seconds hand of a position counter 42 ofthis latter, and which will be described in further detail later,according to the following correspondences: for the entry values 0, 1, 2and 3, the exit values 60, 15, 30 and 45, as has been explained withreference to FIG. 1.

Similarly, the counter 32 is coupled to a month coder 36 which comprisescombinative logical elements which allow the correspondence of thevalues from the month counter 32 with the values corresponding to theimage of the position of the seconds hand of a position counter 42 ofthis latter, according to the following correspondences: for the entryvalues, 1, 2, . . . , and 12, the exit values 05, 10, . . . , and 60, ashas been explained with reference to FIG. 2.

The year coder 35 and the month coder 36 together with the day counter31 and the counter 28 are connected to a signal selector 37 which allowsthe selection of one from these four sources of information: sixtiescounter 28, year coder 35, month coder 36 and day counter 31, selectioncommanded by one of the four entry signals, a, b, c, d, of which thefirst a, is generated by the switch I and the three others b, c and dcorrespond to the three axial positions of the time-setting rod. One ofthe other signals A, B, C, or D, emitted respectively by the counter 28,the coder 35, the coder 36 or the counter 31 is thus directed at theexit of the selector 37 on one of the entries of a comparator 38.

This comparator 38 provides an exit signal to the logical level 1 at oneof the two entries of the door "AND" 27, as long as the entry signalscoming on the one hand from the selector 37 and on the other hand, fromthe position counter of the seconds hand position 42 are different. Oncethe two entry signals are identical, the exit signal reverts to thelogical level 0. This door "AND" is linked by its exit to a commandblock 39 of the motor M. It is designed to assure the excitation of thismotor by steps, each one of which corresponds to a second.

The motor M is linked to a seconds wheel 40 which drives the secondswheel linked to the seconds hand 12. At each step of the motor M theseconds wheel travels a distance corresponding to an angle of 6 degrees,i.e. one sixtieth of a turn.

A detector 41 of the position of the seconds wheel unequivocallydiscriminates a single position of the seconds wheel from the sixtywhich are possible. This particular position corresponds to theorientation of the seconds hand on the index 00 on the face of the watch(12 noon). The exit signal passes to the logical level 1 when thisparticular position is detected; it orders the return to zero of theposition counter 42 of the seconds hand 12.

The position counter 42 of the seconds hand memorises the currentposition of this latter. 00 corresponds to the position 0 on the watchface. The capacity of this counter ranges from, 00, corresponding toposition 0 on the watch face, and 59 corresponding to the position 59 onthe watch face. The state of the counter is given to one of the twoentries of the comparator 38.

The "impulse generator" with--position and rotation sensing element 21transmits the signals X and Y to a rotation detector 43, by means of twocontacts opening and closing sequentially during the rotation of thewinding rod. This rotation detector generates a signal F during ananti-clockwise rotation of this rod; this signal passes from the logicalstate 0 to the logical state 1 and inversely at each opening, orrespective closing of the above mentioned contacts. This signal F ispassed to one of the two entries of each of the three doors "AND" 44,45and 46 whose purpose will be described below.

As mentioned before, the winding rod can move axially between threedistinct positions. One of these three positions is detected by means ofthe selector S which has three contacts providing the signals b, c andd. The sequential opening and closing of the two contacts of the impulsegenerator 21, generates said signals X and Y described above.

The three doors "AND" 44, 45 and 46 have one of their common entrieslinked to the rotation detector 43 of the crown 20. They receive thesignal F generated by this detector. The selector S connects the exit ofa reverser 47 to the other entry of one of the three doors 44, 45 or 46,the two non-connected entries always staying at the logical level "0".

The door "AND" 27 with two entries permits the control of the passage ofthe logical signal of 64 Hz delivered by the frequency divider 25. Ifthe comparator 38 has not detected identitical signals, it provides ahigh level logical signal to one of the two entries of the door "AND";the door allows the signal 64 Hz to pass by the second entry. The signalof 64 Hz orders the advance of the motor and the increase of the counterof the position of the seconds hand, this latter advancing rapidly. Oncethe comparator detects identitical signals, it provides a low levellogical signal; the door 27 no longer allows the signal 64 Hz to bepassed. This has the effect of stopping the seconds hand in the positioncorresponding to the equality detected.

The reverser 47, mentioned before, allows the formulation of the signalcoming from the programming interruptor I. In normal mode, theinterruptor I is connected to the positive supply V_(DD), the exit ofthe reverser being therefore in a low level logical state, consequentlynone of the three doors 44, 45 or 46 can allow the passage of the signalF. The signal at the entry of the reverser and at the entry a of theselector 37 is at a high logical level, the selector choosing the signalA coming from the seconds counter 28. In programming mode, theinterruptor I is connected to the potential V_(SS), representing themass; the exit of the reverser is thus in the logical state "1". One ofthe three signals a, b or c is thus at a high logical level (followingthe axial position of the winder rod). If b is at 1, an anti-clockwiserotation (signal F present) produces an increase in the year counter 33by the signal INC_(B) coming from the door "AND" 44. If c has a value of1, a similar rotation causes an increase in the month counter by thesignal INC_(C), coming from the door "AND" 45, but without result if thecapacity is exceeded (C_(B) is not activated). If d is at 1, a similarrotation causes an increase in the day counter by the signal INC_(D),produced from the door "AND"46, without reply if the capacity isexceeded (C_(C) is not activated).

This form of the embodiment is given by way of a non-limiting example,and even though the functions are perfectly defined and unchangeable inthe frame of the process according to the invention, the components maybe modified or replaced by equivalent components.
